Quick Answer: What Does Source Code Mean?

Why is source code important?

Source code serves the needs of companies who have procedures in place that they want to retain regardless of the software installed.

Some companies consider source code as a way to guarantee that the software changes as their company’s needs change in the future..

Why is it called source code?

Source code is the list of human-readable instructions that a programmer writes—often in a word processing program—when he is developing a program. The source code is run through a compiler to turn it into machine code, also called object code, that a computer can understand and execute.

What is source code example?

An example of source code is someone using HTML code to create a screen. Code written by a programmer in a high-level language and readable by people but not computers. Source code must be converted to object code or machine language before a computer can read or execute the program.

How do you write source code?

To write a source code, all you really need is a simple text editor – like the Notepad on Windows or TextEdit on Mac. This way, source code can be saved as plain text (e.g. in ASCII coding or with UTF-8 encoding) with the correct file name ending for the programming language. So if you find a file with the ending “.

What is meant by source code and object code?

Source code is generally understood to mean programming statements that are created by a programmer with a text editor or a visual programming tool and then saved in a file. Object code generally refers to the output, a compiled file, which is produced when the Source Code is compiled with a C compiler.

What is machine code written in?

binaryMachine code is a computer program written in machine language. It uses the instruction set of a particular computer architecture. It is usually written in binary.

What is Python source code?

Because Python applications are typically distributed as source code, the role of the Python runtime is to convert the Python source code and execute it in one step. Internally, the CPython runtime does compile your code. … It is actually compiled. Python code is not compiled into machine-code.

Who writes source code?

If you’re picturing 1s and 0s flying past your head in a green hue like in The Matrix, you’re not far off. Source code is a set of instructions that a computer program will follow. These instructions are written by programmers or developers as text files.

How is source code hidden?

Compiled languages are the easiest to keep the source code private. The compilation process breaks down every call into very low-level binary codes and reorders instructions. Many function calls may be completely inlined so that they never appear as a function call at all.

Is object code human readable?

Object code is not human understandable. 05. Source code is not directly understandable by machine. Object code is machine understandable and executable.

Where is source code?

The source code which constitutes a program is usually held in one or more text files stored on a computer’s hard disk; usually these files are carefully arranged into a directory tree, known as a source tree. Source code can also be stored in a database (as is common for stored procedures) or elsewhere.

What is page source code?

What is the difference between source code and compiled code?

Source Code Gets Converted Before It Can Run. … Compiled languages is when a person writes the code, compiler separates the file and the end result is an executable file. Basically, owner keeps the source code. Interpreted languages are different because the code is not compiled first hand.

What is the difference between source code and executable code?

Source code is what humans can read, write and understand. Object code is what some computer programs produce from Source code. Executable code is what computers can execute.

What is compiled source code?

Compiled source code starts as text files. Text is then transformed into machine code instructions by a corresponding compiler for performance boosts over code that is otherwise interpreted at run time.
